Co., MN �� � <br /> � <br /> A Compliance Inspection was compteted for the existing on-site sewage treatment <br /> system located on this property. Soil borings # 1A & 2A found mottled soil (redox <br /> features) at 38" & 36" below the ground surface. Soil probings into the system found <br /> gravelless pipe with the bottom of the pip� at 28" to 40" below grade. The system does <br /> not meet the required separation from the bottom of the system & redox features & is <br /> classified as non-compliant, failing to protect the ground water. <br /> This on-site sewage treatment system is clesigned for a Type 1, three bedroom home, <br /> in accordanc�� with the Minn�sota Pollution Control Agency Chapter 7080 and local <br /> ordinances. <br /> The soils on this site are a loam. The seasonally saturated soils were located at 32" to <br /> 38" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound System <br /> will need to be installed to treat septic effluent. The bottom of the rock must be located <br /> at least 3' above the saturated soils. <br /> The soils at a depth of 12" have a percolation rate of 15.0 mpi. 4R4N0 COI'� <br /> The existing tanks may be used if water tic�ht. If the tanks cannot be used, abandon, <br /> pump & remove the tanks & install 2-1000 gallon tanks. <br /> A pumping chamber will need to be installsd to lift the effluent to the treatment area. <br /> The power supply and switches must be lacated outside the manhole and pumping <br /> chamber in a weather proof enclosure. A warning device must��talle��v�t���ight <br /> and sound device, this is in case of a pump failure.
